This research program in water resources engineering provides a number of opportunities to investigate questions in the emerging field of eco-hydraulics. This proposal has three main projects: 1) Fish Passage and Habitat Structures in Rivers; 2) Turbulent Jets in Hydraulic Engineering; and 3) Environmental Hydraulics. Fish passage and habitat structures in rivers: Fish passage past either man-made or natural obstructions in rivers is important for the survival of fish in our rivers. My research group has made significant contributions to the design of various fishways (e.g. pool and weir, Denil, vertical slot and culvert fishways) so that these can be designed for most situations. We have made a preliminary contribution to one type of nature-like Boulder ramp fishway, and we want to develop a general design of and also study the Riffle-Pool type during the next five years. Turbulent jets are very important in the design of hydraulic structures. We studied the hydraulics of submerged jump stilling basins and want to develop a standard basin for submerged flows below hydraulic structures. We have developed a general analysis of circular hydraulic jumps and plan to develop a general design for practical use. We are also studying slurry jets to help in the reclamation of oil sands ponds in Northern Alberta and to make a general contribution to two-phase turbulent jets. This project has the potential for the remediation of granular nuclear wastes. Environmental hydraulics: We have studied and helped design plungeflow dropshafts in the City of Edmonton's drainage system. We plan to improve these designs to reduce odour problems in the drainage systems. These studies will be done in collaboration with the City of Edmonton, which may increase its practical application in other municipalities.

该水资源工程研究项目为研究新兴生态水力学领域的问题提供了许多机会。本方案主要包括三个项目：1）河流鱼类通道和栖息地结构； 2）水利工程中的湍流射流； 3) 环境水力学。河流中的鱼类通道和栖息地结构：鱼类通过河流中的人造或自然障碍物对于河流中鱼类的生存非常重要。我的研究小组对各种鱼道（例如水池和堰、丹尼尔、垂直槽和涵洞鱼道）的设计做出了重大贡献，因此这些鱼道可以针对大多数情况进行设计。我们已经对一种类似自然的博尔德坡道鱼道做出了初步贡献，我们希望在未来五年内开发和研究 Riffle-Pool 类型的总体设计。湍流射流在水工结构的设计中非常重要。我们研究了水下跳跃消力池的水力学，并希望开发一个用于水工结构下方水下流的标准水池。我们已经对圆形液压跃迁进行了总体分析，并计划开发出实用的总体设计。我们还在研究泥浆射流，以帮助改造阿尔伯塔省北部的油砂池，并对两相湍流射流做出总体贡献。该项目具有修复粒状核废料的潜力。环境水力学：我们研究并帮助设计了埃德蒙顿市排水系统的切入式落轴。我们计划改进这些设计，以减少排水系统中的气味问题。这些研究将与埃德蒙顿市合作进行，这可能会增加其在其他城市的实际应用。
